Detailed Description

class defining a representation for the vtkTensorWidget

This class is a concrete representation for the vtkTensorWidget. In summary, it allows the editing of a tensor glyph (by modifying the underlying tensor value). This includes controlling the position, scaling, and rotation of the glyph. The representation is simply an oriented, scaled box which can be manipulated to transform the tensor. Optionally, an ellipsoid defined by the tensor eigenvectors can be shown for informational purposes.

To use this representation, specify a 3x3 real, symmetric matrix defining the tensor. (This implicitly defines an orthogonal basis from the three tensor eigenvectors.) Then use PlaceWidget() to define a bounding box: the bounding box defines a position for the tensor from its center point, and the representation is scaled to fit in the bounding box.

Note: typical usage is to place a tensor glyph inside of the representation (i.e., the box) which is updated as the representation is manipulated by the user. The built-in ellipsoid can be used for this; alternatively through callbacks and such, it is possible to place other glyph types such as superquadrics.

◆ SetTensor()

void vtkTensorRepresentation::SetTensor ( double tensor[9] )

These are the basic methods used to define the tensor (these methods coordinate with the overloaded PlaceWidget() method).

The methods enable specification of a 3x3 symmetric tensor. This information is used to construct an oriented, appropriately ellipsoid that is (initially) centered and fits inside the bounding box defined by PlaceWidget(). As this widget is modified during user interaction, the tensor data member is continuously updated and can be queried. Note that a symmetric tensor can be defined with only six components. If a full 3x3 tensor is specified, only the symmetrical part of the tensor is used since the extracted eigenvalues/eigenvecters are required to be real valued. When a tensor is specified, the derived information (e.g., eigenvalues/vectors and position) are immediately updated.

◆ SetSymmetricTensor()

void vtkTensorRepresentation::SetSymmetricTensor ( double symTensor[6] )

These are the basic methods used to define the tensor (these methods coordinate with the overloaded PlaceWidget() method).

The methods enable specification of a 3x3 symmetric tensor. This information is used to construct an oriented, appropriately ellipsoid that is (initially) centered and fits inside the bounding box defined by PlaceWidget().

void vtkTensorRepresentation::SetPosition ( double pos[3] )

Set/Get a position for the location of the tensor.

◆ GetPolyData()

void vtkTensorRepresentation::GetPolyData ( vtkPolyData * pd )

Grab the polydata (including points) that define the representation.

The polydata consists of 6 quadrilateral faces and 15 points. The first eight points define the eight corner vertices; the next six define the -x,+x, -y,+y, -z,+z face points; and the final point (the 15th out of 15 points) defines the center of the box. These point values are guaranteed to be up-to-date when either the widget's corresponding InteractionEvent or EndInteractionEvent events are invoked. The user provides the vtkPolyData and the points and cells are added to it.
